Hewitt talks of hope and hallucinations

In his 75 hour ordeal at sea diver Robert Hewitt suffered hallucinations, believing he was home with his fiance and children.
Hewitt, 38, a former Royal New Zealand Navy diver and brother of ex All Black Norm Hewitt, was found alive yesterday after going missing on a diving expedition near Porirua on Sunday.
He was found near where he went missing yesterday afternoon, his survival hailed as a miracle.
Mr Hewitt said from his hospital bed that he had drifted as far as Waikanae 27km to the north, then back to the vicinity of Mana Island, where his ordeal had begun.
As time went on without rescue he became disillusioned, but his attitude got him through.
"It's one of those things you have to have a good sense of humour, you know, look at the bright side of things," he told NewstalkZB's Paul Holmes from his hospital bed.
"I must say I was dying of thirst, but you look at the young kids overseas who haven't got water to drink so I just put myself in a mental state like that."
But towards the end of his ordeal Mr Hewitt began suffering hallucinations.
"I honestly thought yesterday afternoon I was at home. I started taking off some of my gear, here and there, floundering around like I was lost.
"I honestly thought I was at home with my fiance, Rangi, and my kids and I'd just come back from diving and I said `Sorry I'm a bit late'."
"The first day was good and then watching the aircraft shoot away and then coming into my first sunset. . . it hurt quite a bit.
"Once I spent my first night there I thought `right, it's going to be a bit longer than I thought'," Mr Hewitt said.
He had no water to drink, but managed to survive by eating crayfish and kina he had collected before his dive went wrong.
"Just one crayfish and four kina, after the first night I knew I had enough sustenance for 24 hours," he said.
"With the food, I shed a few kilos, but maybe they were the kilos that needed to be shed," he laughed.
Mr Hewitt said he did not have much time left, when rescued about 4pm yesterday.
"Honestly with the hallucinations that I had, especially yesterday, I don't think I would have made last night."
But he joked about returning to the area soon.
"Nah, I didn't bring a cray back I'll have to go out next week and try and get the big fulla I saw down there."
Mr Hewitt thanked his fiancee and family and all the well-wishers.
He was found by former navy colleagues in misty, rainy conditions, 400m northeast of Mana Island, near the entrance to Porirua Harbour.
The police launch Lady Elizabeth III took him to Mana Cruising Club where he was taken to Wellington Hospital by ambulance after a brief reunion with family.
Despite an intensive air, land and sea search, almost everyone had given Mr Hewitt up for dead.
Brother Norm Hewitt said today the family had never given up hope because the goal either way was to bring Robert home either dead or alive.
The air search was called off on Tuesday, but a Royal New Zealand Navy team of eight divers was brought in.
It was Chief petty officers Lyle Cairns and Buzz Tomoana, personal friends of Mr Hewitt's, who spotted him floating in a sheltered cove near the spot he went missing."
